Answer 1

您可以从使用C ++

逐行处理文件开始

string line;

while (getline(file, line)) {
    line.erase(remove(line.begin() + line.find_first_of(' '), line.end()), line.end());
    ... // do anything with line
}

由于您已标记notepad++，因此它可以运行python脚本。尝试

file = open('logfile_name')
for line in file:
    print line.split()[0]

了解如何在notepad ++中运行python脚本并使用它。

删除所有但第一个字符串
